Penggunaan Plugin

Plugin dapat menjalankan kode untuk jangka waktu tertentu, dan dapat melakukan beberapa operasi sederhana, sepertipesanan gunung es, Perintah yang menunggu, pembatalan pesanandanPerhitungan pesananSama sepertialat debugging, itu menggunakanreturnuntuk mengembalikan hasil, dan juga dapat secara langsung mengembalikan grafik dan tabel. Berikut adalah beberapa contoh, dan fungsi lain dapat dijelajahi sendiri.
